CORNER IRON OR STRAP FOR CARS.

SPECIFICATION forming part of Letters Patent No. 644,017, dated February20, 1900.

Application filed October 6, 1899.

To all whom it nuty concern.-

Be it known that I, ISAAC L. KISER, a citizen of the United States,residing at Little Rock, in the county of Pulaski and State of Arkansas,have invented new and useful Improvements in Corner Irons or Straps forCars, of which the following is a specification.

My invention relates to corner irons or straps for cars, the objectthereof being to provide a strengthening device of this 'character inwhich the corner-strap or angle-iron and its attaching or clampingdevices are all constructed and arranged in such a manner as to impartincreased strength, decrease the cost of production, and give greaterdurability and solidity to the cars on which-such straps are employed.

To enable others to clearly understand and to successfully practice mysaid invention, I will now proceed to describe the same in detail, andfollowing said description will particularly point out in the claims thenovel features which constitute my invention. For the purposes of saiddescription reference is .had to the accompanying drawings,in which--Figure 1 is a sectional plan showing a corner-iron constructed inaccordance with my invention and applied to a car. Fig. 2 is aperspective view of the corner-iron and clamping-rod removed from thecar. Fig. 3 is a view of one of the exterior angles of a car, showing myinvention. Fig. A is a View showing a modified construction of thecorner-iron.

The reference-numeral 1 in said drawings indicates the body of anyordinary car, the corner only being shown, with its post 2 and the sidebelt-railand end belt-rail 3 and 4, Fig. 1.

My corner-iron consists of an angle-plate or corner-strap 5, of suitablewidth and length and thick enough to impart the necessary In said strapat corresponding points on opposite sides of the angle are formedopenings 6 for the ends of a clampingrod 7, the ends of said rod beingthreaded to receive nuts 8.

The corner-iron is applied to the outer face of the car at the angles,the ends of the rod 7 being inserted in holes bored in the sills,belt-rails, and top plates of the car. This is readily effected, sincethe ends of the clampin g-rod are parallel with each other, as shownSerial No. 732,808. (No model.)

in Fig. l. The ends of the clamping-rod project into'recesses 9 in thesills and in the side and end belt-rails, respectively, and receive nuts8, which are screwed up, and thereby drawn into said recesses, so thatthere are no sharp projecting points or angles at the interior cornersof the car.

When applied at the lowest point on the car, I may make the corner ironsor straps 5 wider, as shown in Fig. 3, and in such a case thecorner-iron may have two or more clamping-rods to secure it in place.

By constructing a corner-strap in the manner shown I am able to secure ahigh degree of strength and stiffness without increase of weight. Thecorner iron or strap has a much more ornamental and graceful appearancewhen secured in place by the clamping-rod 7, as no bolt-heads appearupon the outer face of the strap. Moreover, the latter is not weakenedby the formation of numerous holes for receiving a series ofattaching-bolts.

I may construct the corner iron or strap 5 in the manner shown in Fig.4-that is to say, with an end extended and provided with a crimp 10,formed in it for the end of a truss, a single perforation 12 being madethrough the crimp.

As shown in Fig. 3, it is preferable to apply the corner irons or straps5 to the outside of an ordinary car at points corresponding with thelocation of the car-sills, belt-rails, and top plates; and the holes forpassage of the screw-threaded ends of the clamping-rods 7 are extendedthrough the sills, belt-rails, and top plates at an angle of aboutforty-five degrees, corresponding with the angles formed by the ends ofeach clamping rod. The clamping-rod 7 is circular in cross-section andis formed with three bends, as shown, the two ends of the rod beingparallel and provided with screw-threads for engagement of the nuts 8,that secure the straps 5 and rods 7 in place. The thickness, width, andlength of the corner-straps 5 will correspond with the dimensions of thecar-sills, belt-rails, and top plates at the points where thecornerstraps are applied. It is preferable to make the strap-openings 6oblong, as shown in Fig. 4, thereby facilitating application of theclamping-rod 7 and its straining by the nuts 8, so'as to secure thecorner-straps firmly.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. A corner iron, or strap, for cars, consisting of an angle-platehaving openings in its end portions, in combination with a clamping-rodhaving parallel screw-threaded ends and provided with the describedbends,whereby the said rod is adapted to be applied along the outside ofsaid corner-iron and With the parallel ends of the rod extended throughthe openings in the corner-iron, and nuts on the screw-threaded ends ofsaid rod,substantially as described.

2. A corner iron, or strap, for cars, consisting of an angle-platehaving oblong openings near its ends, in combination with a clamping-rodapplied to the outside of said corner-iron and provided with parallelscrewthrcaded ends projecting through said openings at an angle of aboutforty-five degrees, and nuts on the screw-threaded portions of the rodends, substantially as described.

3. The combination with a corner iron, or strap, for cars, of aclampingrod having bends, as described, and provided with parallelthreaded ends to project through openings in said corner-iron, and nutson the threaded ends of said clamping-rod, substantially as described.

4. The combination with a car, of a corneriron consisting of anangle-plate having openings near its ends, a clamping-rod provided withbends and having parallel screw-threaded ends to project through theopenings of said corner-iron and through openings in the sills orbelt-rails of the car, and nuts turned onto the screw-threaded ends ofsaid rod and adapted to rest in recesses in the inner faces of thebelt-rails and sills of the car, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

ISAAC L. KISER.
